WILLIAM H. PECKHAM, OF BIG SPRINGS, KANSAS.

IMPRPVEMENT IN EVE-GLASSES.

Specification forming part of Letters Patent No. 165,251, dated July 6,1875; application filed June 9, 1875.

To all whom it may concern Be it known that I, WILLIAM H. PEGKHAM, ofBig Springs, in the county of Douglas and State of Kansas, have inventeda new and useful Improvement in Spring Eye-Glasses; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings forming a partof this specification.

The nature of myinvention consists in having a 'hollow slot through thepost through which the nose-sprin g passes and rests against a shoulderformed by the spring. After passin g the nose-spring through the slot, asmall spring which forms a part of the nose spring, catches under or onone side of the slot in the post thereby preventing the spring from'falling out or getting loose in its place.

In the accompanying drawings, Figure 1 is an elevation of a pair ofeye-glasses constructed according to my improvements. Fig. 2 is a detailof a part of the nose-spring, showing the small spring which fastens itto the post of the glass-bow or frame. Fig. 3 is a detail of a part ofthe frame. A A is the frame; B B B, the nosespring; c c, the smallsprings which hold the nose-spring in its place; (Z d, the posts of theframe containing slots through which the nose-spring passes. E E is alug, which forms the base in which the ends of the nose-spring B rest.

This mode of fastening is so' simple in its construction that, shouldthe nose spring break, it can be readily removed by any pen son, eventhe most inexperienced, by merely pushing in the small spring in thenose-spring underneath the post attached to the rim of the eyeglass anddrawing out the nose-spring from the slot through which it passes. Thelug E, forming the base upon which the nosespring rests, has a hole orslot in the same which receives the end of the nose-spring, so as togive stability and strength to the entire length and breadth of the saidspring. The surface of the bearing-spring, or that part which spring c,in combination with slotted post d and lug E, substantially as shown anddescribed, and for the purpose specified.
